Anatomy and Physiology Of Sciatic Nerve Origin and Branches of the Sciatic Nerve: The sciatic nerve starts in the lower spine and follows a long path through the buttock, down the back of the thigh and leg, and finally ends in the foot. Origin of Sciatic Nerve : The sciatic nerve is formed by the…
The radial nerve is a major peripheral nerve of the upper limb. The radial nerve is a nerve in the arm that provides sensation to the skin on the back of the hand and the thumb side of the forearm. It is the largest nerve in the upper arm, and is a mixed nerve. The…
Coarctation (ko-ahrk-TAY-shun) of the aorta — or aortic coarctation — is a narrowing of the aorta, the large blood vessel that branches off your heart and delivers oxygen-rich blood to your body. When this occurs, your heart must pump harder to force blood through the narrowed part of your aorta. Coarctation of the aorta is…
PATENT DUCTUS ARTERIOSUS PDA is a heart problem that is frequently noted in the first few weeks or months after birth. It is characterized by the persistence of a normal fetal connection between the aorta and the pulmonary artery which allows oxygen-rich (red) blood that should go to the body to recirculate through the lungs….
A ventricular septal defect (VSD), a hole in the heart, is a common heart defect that’s present at birth (congenital). The hole (defect) occurs in the wall (septum) that separates the heart’s lower chambers (ventricles) and allows blood to pass from the left to the right side of the heart. The oxygen-rich blood then gets…
OVERVIEW An atrial septal defect (ASD) is a hole in the wall between the two upper chambers of your heart (atria). The condition is present at birth (congenital). Small defects may never cause a problem and may be found incidentally. It’s also possible that small atrial septal defects may close on their own during infancy…
INTRODUCTION Cardiomyopathy is a disease of the heart muscle that makes it harder for your heart to pump blood to the rest of your body. Cardiomyopathy can lead to heart failure. The main types include dilated, hypertrophic and restrictive cardiomyopathy. Treatment — which might include medications, surgically implanted devices or, in severe cases, a heart…
DEFINATION Congenital heart disease, or a congenital heart defect, is a heart abnormality present at birth. The problem can affect: The heart walls The heart valves The blood vessels There are numerous types of congenital heart defects. They can range from simple conditions that don’t cause symptoms to complex problems that cause severe, life-threatening symptoms….
DEFINATION CONGESTIVE HEART FAILURE(CHF) is a chronic progressive condition that affects the pumping power of your heart muscles. While often referred to simply as “heart failure,” CHF specifically refers to the stage in which fluid builds up around the heart and causes it to pump inefficiently. Heart failure does not mean the heart has stopped…
What is a Cardiac Arrest? Cardiac arrest is a serious heart condition. The word arrest means to stop or bring to a halt. In cardiac arrest, the heart ceases to beat. It’s also known as sudden cardiac death. Your heartbeat is controlled by electrical impulses. When these impulses change pattern, the heartbeat becomes irregular. This…
